Trivia

The ERTL models for the caterpillar cranes incorrectly refers to them as a 'he' as if there is only one of them and as if they're sentient.

It's likely that the Caterpillar Cranes may have been intended for Thomas & Friends' sister show, TUGS, as they are more detailed than most of the other vehicle props, and were possibly made shortly before TUGS' cancellation.
